responsive_builder

• Fixes #53

• Fixes #50

• Fixes #48

• Fixes bug with preferDesktop and getValueForScreenType

• Fixes bug with preferDesktop where it always returns desktop UI even if there is a mobile UI.

• Adds preferDesktop to ResponsiveApp which tells the builders that if there's no layout supplied for the current size prefer the desktop over the mobileLayout. Default value is false to maintain mobile first behaviour.

New Feature

Adds responsive sizing by using the ResponsiveApp widget at the highest level which allows:

• Using 20.screenHeight / number.screenHeight shorthand to get the percentage of the Screen Height
• The same exists for the screenWidth
• There are also shorthand extensions for both. screenHeight => sh and screenWidth => sw

• Adds checks to ensure desktop returns as Flutter web

New Feature

Adds the ScrollTransform functionality which allows you to more easily create scroll effects based on the scrolling position.

• Adds banner to readme

• Added small size for getValueForRefinedSize
• Adds funding link to coffee

• Added optional override property in orientation builder

• Adds null safety and correct small refined sizing

• Adds the refined sizing functionality

• Adds responsive sizing config for global breakpoint setting

• export the sizing config which I forgot to do first time.

• Added getValueForScreenType functionality to the readme

• Reverted the change for returning the mobile layout when break points doesn't define any.

• Changed enum naming to lowerCamelCase to follow convention
• Add a return for mobile when no breakpoints match

• readme updates

• Made 600 inclusive for tablet devices and 900 inclusive for desktop

• Added ScreenTypeValue builder to allow us to return different values depending on the screen type

• Added optional screen break points definition to pass in to the ResponsiveBuilder or the ScreenLayoutView.

Changelog styling updates

• Added shorthand bool properties to sizing information to check which device screen type is currently being show.

• Updated screen type calculation to account for being on the Web. Width was swapping with the height when it got too wide so we're checking for web explicitly and using the width of the window.

• Update the ScreenTypeLayout widget to use an incremental layout approach. If the desktop isn't supplied and we're in desktop mode we check if there's a tablet layout and show that, otherwise we show the mobile layout.

• Added initial widgets required for a clean responsive UI architecture.
